Patent GB-853194-A (GB)
Title: Process for the production of shaped parts of plasticized polyolefins
IPC: B29C43/00
Filed: 1957-10-18
Abstract: A moulded part of a polyolefin is produced by compressing a finely divided polyolefin or mixture of polyolefins to yield a shape-retaining pressing, and bringing at least two such pressings together under heat and pressure to yield a single part.  The process is primarily applicable to the moulding of polyethylene having a molecular weight above 100,000 and preferably above 500,000, but plasticised polypropylene may also be used.  The pressings may be in the form of rectangular prisms or circular discs, and may be of different colours for producing bodies of variegated colouring.  In one example slabs of polyethylene of molecular weight 1,100,000 are formed by compressing particles in a die at 100 kg./sq. cm. pressure and at room temperature.  Twenty slabs are placed side by side in a die and heated to 150 DEG C. for 6 hours under 10 kg./sq. cm. pressure to obtain a homogeneous sheet, alternatively the slabs may be heated prior to placing in a die and not or only slightly heated during the pressing.  In a second example the slabs are placed one upon the other.

Abstract: 738,092. Water-tube steam boilers; steam superheaters. BABCOCK & WILCOX, Ltd. Dec. 18, 1953 [Dec. 23, 1952], No. 32677/52. Classes 123 (2) and 123 (3). A steam &c. boiler has a furnace chamber 1 fired by burners 41 and lined with closely-spaced steam generating tubes which extend between lower headers 11, 18, and a steam and water drum 14, the upper part of the chamber locating a radiant superheater 47 and having a gas outlet 19 into a lateral pass 60 which leads at its rearward end 62 into a vertical downpass 61, the end 62 projecting over the downpass for about half the depth of the latter. The floor of pass 60 has two inclined parts 65a, 65b which together form a funnel or hopper extending the whole width of the pass and leading into a vertical shoot and gas by-pass 67 disposed at the front side of downpass 61 and separated therefrom by a tube wall 82. The end 62 of pass 60 and the whole of downpass 61 are divided by vertical tube walls 72, 73 into three gas flow paths 61a, 61b, 61c, the lower ends of which have lateral outlets 74a, 74b, 74c respectively controlled by dampers 200a, 200b, 200c and leading into a common downward extension 85 which locates economizer sections 205a, 205b, 205c. The bottom of by-pass 67 is connected by tunnels 86, Fig. 7, having dampers 202a, 202b to the extension 85, a flue 206 connecting the lower part of the extension to the boiler stack. The downpasses 61a, 61b, 61c each locate three superposed banks of horizontal tubes such as 137a, 137b, 137c, Fig. 1, those in the outer passes constituting primary superheater sections and in the middle pass, reheater sections. The sections are connected respectively to banks 137d, 147d and 183b of  pendant tubes which are disposed above the floor portion 65b, these banks being connected to further banks 137e, 147e and 183a located above by-pass 67. The secondary superheater consists of banks 157a, 157b of pendant tubes disposed in the forward part of pass 60. Saturated steam from drum 14 passes serially through superheater 47, tubes lining the downpass 61 and forming the dividing walls 72, 73 and 82 and the primary and secondary superheaters, between which an attemperator 151 is disposed. Superheat temperature is controlled by regulation of the attemperator and of the gas flow through by-pass 67 whilst reheat temperature is controlled by regulating the distribution of gas between the outer and middle downpasses. In operation, deposits which build up on the pendant tubes are periodically removed by injection of cleaning fluid, the construction providing, by the location of the inclined floor 65b under tube banks 137d, 147d and 183b, that solid matter dislodged from these banks does not fall into the downpasses to foul the tube banks therein, but is diverted into by-pass 67 wherein it falls into hopper 94 from which it may be periodically removed.
